Intelligent Networking Features for a Scalable, Manageable Solution

The Cisco Aironet 350 Series extends end-to-end intelligent networking to the wireless access point with support for

enterprise-class virtual LANs (VLANs) and quality of service (QoS). An ideal choice for enterprise installations, the

Cisco Aironet 350 Series can manage up to 16 VLANs (Figure 2), which allows customers to differentiate LAN

policiesand services, such as securityand QoS, for different users.For example, enterprise customers canuse different

VLANs to segregate employee trafﬁc from guest trafﬁc, and further segregate those trafﬁc groups from high-priority

voice trafﬁc. Trafﬁc to and from wireless clients with varying security capabilities can be segregated into VLANs with

varying security policies. For example, VLANs allow educational institutions to secure faculty and administrator

trafﬁc from student trafﬁc traveling over the same infrastructure. Implementing VLAN segmentation increases

wireless LAN manageability and security.

Figure 2 Indoor Wireless VLAN Deployment

With support for 802.1p QoS, the Cisco Aironet 350 Series provides trafﬁc prioritization for packets traveling to

and from the access point over Ethernet. Delay-sensitive trafﬁc, such as voice and video, can be prioritized over

data trafﬁc for improved user experience and optimal network utilization. Software and radio ﬁrmware upgrades

provide the capability to upgrade to future QoS standards such as 802.11e. Supporting the voice prioritization

schemes for 802.11b mobile phones, the Aironet 350 Series further enables quality voice-over-wireless-LAN

solutions.

Industry-Leading WLAN Performance, Range, and Reliability

The 100-mW transmit power and receive sensitivity of the Cisco Aironet 350 Series AP leads the industry in range

and reliability. Antenna diversity and superior delay spread (multipath) characteristics of the Cisco Aironet 350 Series

deliver improved performance even in harsh environments such as warehouses, factories, and metal buildings.

Administrators can conﬁgure the radio transmit power (1, 5, 20, 30, 50, and 100 mW) on the Cisco Aironet 350

Series to meet speciﬁc coverage requirements and minimize interference. In addition to an AP with two captured 2.2

dBi antennas, an AP with two RP-TNC connectors is offered for more challenging applications, where a broad

portfolio of removable antennas can be used to further increase range and reliability.

Investment Protection

To protect the users’ investment, all Cisco Aironet 350 Series APs and bridges feature sufﬁcient Flash memory to

handle future ﬁrmware upgrades.

Enterprise-Class Wireless LAN Security

Wireless LAN security is a primary concern. The Cisco Aironet 350 Series secures the enterprise network with a

scalable and manageable system featuring the award-winning Cisco Wireless Security Suite. Based on the 802.1X

standard for port-based network access, the Cisco Wireless Security Suite takes advantage of the Extensible

The Cisco Wireless Security Suite interoperates with a range of client devices. It supports all 802.1X authentication

types,includingEAPCisco Wireless(LEAP), ExtensibleAuthenticationProtocol-TransportLayer Security (EAP-TLS)

and types that operate over EAP-TLS, such as Protected Extensible Authentication Protocol (PEAP), EAP-Tunneled

TLS (EAP-TTLS) and EAP-Subscriber Identity Module (EAP-SIM). A wide selection of Remote Access Dial-In User

Service (RADIUS) servers, such as the Cisco Secure Access Control Server (ACS), can be used for enterprise-class

centralized user management that includes:

• Strong, mutual authentication to ensure that only legitimate clients associate with legitimate and authorized

network RADIUS servers

• Dynamic per-user, per-session encryption keys that automatically change on a conﬁgurable basis to protect the

privacy of transmitted data

• Stronger WEP keys provided by pre-standard Temporal Key Integrity Protocol (TKIP) enhancements such as

message integrity check (MIC), per-packet keys via initialization vector hashing and broadcast key rotation

• RADIUS accounting records for all authentication attempts.

Integrated Management for Configuration, Monitoring, and Troubleshooting

The Cisco Aironet Series offers simpliﬁed installation and conﬁguration, for rapid, anytime, anywhere installation,

conﬁguration, and management (see Figure 7). The series supports Web-based management and Simple Network

Management Protocol (SNMP) features to aid monitoring, troubleshooting, software download, and event logging.

The frequency agility option of the Cisco Aironet Series takes the guesswork out of channel conﬁguration. In this

mode, the AP automatically scans the area and selects the least-congested channel. The installer does not need to be

aware of the settings of other Cisco APs in the coverage area. For enterprise management, the Cisco Aironet Series

providessupport for Cisco Discovery Protocol(CDP) to enable auto discovery ofCisco Aironet APs and bridgesusing

Cisco enterprise management applications such as CiscoWorks2000. Additionally, Cisco Aironet APs support

standard SNMP Management Information Base (MIB) II, Cisco Aironet Series private MIB, and 802.11b MIB.

Cisco Aironet Series APs can also be managed via the console or the Telnet interface.

basic conﬁguration of the access point.

Industry-Leading WLAN Performance and Scalability

All Cisco Aironet Series APs feature load-balancing services. Up to three APs, conﬁgured for different channels,

can be colocated to achieve aggregate peak capacity of 33 Mbps for a single coverage area. Load-balancing policies

based on number of users, error rates, and signal strengths redistribute users to deliver more balanced collision

domains—improving overall performance for installations covering a large number of users.

Broadcast and multicast ﬁltering also enhance scalability. Filtering allows administrators to select the amount of such

frames that enter the WLAN, conserving the shared bandwidth. Layer 3 IP Net and IP Socket ﬁlters are also provided.

Reliability and High-Availability that Enterprise Installations Count On

For business-critical deployments, a Cisco Aironet AP can be conﬁgured as a redundant hot standby to another

AP in the same coverage area. The hot-standby AP continually monitors the primary AP on the same channel, and

assumes its role in the rare case of a failure of the primary AP.

Comprehensive WLAN Solution

Cisco offers a comprehensive WLAN solution including APs and bridges, a variety of client adapters

supporting all popular operating systems, a broad selection of antennas, as well as a security server and

enterprise management applications.

Because it is a part of the Cisco Aironet Series, the Cisco Aironet 350 AP delivers the high level of security,

manageability, scalability, and cost-effectiveness needed to deliver ubiquitous enterprise wireless services that extend

user mobility and enhance overall productivity. Table 1 provides speciﬁcations on the Cisco Aironet 350 Series AP.
